ICL briefing paper estimates that 52% of all small particle pollution from road transport comes from tires and brakes

Green Car Congress

A new briefing paper from Imperial College London estimates that in 2021, 52% of all small particle pollution from road transport came from tires and brakes. Tire wear particles pollute the environment, the air we breathe, the water run-off from roads and has compounding effects on waterways and agriculture.

Chalmers study finds ship exhaust gas scrubbers responsible for up to 9% of certain hazardous emissions into Baltic Sea

Green Car Congress

New research from Chalmers University of Technology, Sweden, finds that the discharge water from ships’ exhaust gas treatment systems—i.e., For many years, we’ve flagged the fact that scrubbers account for disproportionately large emissions of hazardous and acidifying substances into the marine environment.

Two-year study in Canada finds large trucks disproportionately contribute to higher levels of black carbon pollution

Green Car Congress

Researchers found that air pollution levels right beside a major trucking route within a city were close to levels seen beside Highway 401, despite the road carrying less than one-tenth of the vehicle traffic. Research consistently links traffic emissions to negative effects on both the environment and human health. Jonathan M.

Economists propose use of dynamic road fees for traffic control

Green Car Congress

This would contribute to avoiding traffic jams and protecting the environment, the researchers argue. Fees that respond to traffic volumes in real time and with site precision, taking into account factors such as vehicle type and exhaust emissions, can significantly improve traffic flow and contribute to reducing air pollution, they suggest.
